CAR-DOOR.

Specification; of Letters Patent.

Patented Feb. 13, 1917.

Application filed July 14, 1915. Serial No. 39,828.

To all whom it may concern:

Be it known that I, JAMEs IV. BUMsEY, a citizen of the United States of America, and a resident of est Berkeley, county of Alameda, State of California, have invented certain new and useful Improvements in Car-Doors, of which the following is a full and clear specification, reference being had to the accompanying drawings, in which is represented a horizontal sectional view of a sufiicient portion of a doorway to illustrate my invention.

This invention has relation to railway cars in which the door slides horizontally back and forth across the door opening, and when closed is clamped or crowded into close contact with the door frame structure for the purpose of preventing admission of moisture, etc., into the car; the present improvements are intended to provide simple means for effectively sealing the rear end of the door against the admission of moisture, air, dust, etc., as more fully hereinafter set forth, the invention being especially, though not exclusively, applicable to refrigerator cars.

In the drawing, only the right hand portion of the door structure is illustrated, the door being designated by a, the side of the car by b, and the metal door post by c, this post being provided along its outer vertical edge with a flange or plate-like extension (Z whose front face lies parallel with the side face of the car. Between this plate (Z and the adjacent face of the car wall is clamped, by means of a bolt or bolts 6 or otherwise, a fibrous packing strip 7 which consists preferably of a body of feltinclosed in canvas. The outer edge of thispacking strip projects beyond a shoulder 9 formed in the inner face of'the plate (I, so that be tween the reduced edge of the plate (Z and the outer edge of packing f is formed a longitudinal pocket.

Aflixed to the inner face of the door is a metal strip 71, having a flange 71 extending along the vertical rear edge of the door, suitable bolts or rivets y' being employed for affixing this angular metal member to the rear edge of the door. Clamped between the strip h and the inner face of the door is packing strip 70 preferably consisting of a body of felt covered with canvas and terminatmg short of the forward edge of plate It and the rear face of the door.

With a structure such as described, when the door is slid into closed position, the for-' ward edge of the plate It will enter the socket or pocket formed by the projecting edge of packing strip in and abut against shoulder g, while the reduced edge (Z of plate cl will enter the pocket formed under the free edge of plate It and abut against the packing strip 70, thereby forming athoroughly compact joint throughout the length of the rear edge of the door. With this joint, it will be seen that for moisture, etc., to pass the same it will have to take a very'circuitous passage in which there are practically three sealing points, namely, where member cl abuts against packing h, where the front edge of the plate 71, abuts against shoulder g, and where the packing f bears against the inner face of plate It. WVith a joint of this character, it would be practically impossible for moisture to enter the car, even should the space between member h and the car wall be flooded by heavy rains and wind pressure. This joint will also, when used in refrigerator cars, aflord a practical seal against admission of Warm air, dust, etc.

Having thus described my inventioinwhat I claim is: 7

1. In combination with a car wall and a door post structure embodying an abutment 7' plate supported at a distance from the outer face of the car wall, said abutment plate being provided with a longitudinal shoulder along its inner face, a packing strip clamped between said abutment plate and the adja the shoulder thereon and the packing held thereby, and another packing strip clamped of the door, for the-purpose set forth.

2. In combination, a car'wall anda door post structure having an abutment" plate 7 supported at a distance from the outer face between said metal stripandthe inner face the edge of the abutment'plate, for the purpose set forth.

In testimony whereof I hereunto afliX my signature in the presence of two Witnesses.

of the car wall, a packing strip being clamped against the face of the car Wall by said abutment plate, a car door having clamped on its inner face a metal strip adapted to overlap the abutment plate and engage the packing strip therebehind, and a packing strip clamped against the door by said metal strip and adapted to contact with Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. 0.
